Although more research on the vaccine needs to be completed, this news gives hope to individuals who are forced to love felines from afar. So how exactly does it work? In short, a cat gets injected with a vaccine that lowers the amount of Fel d 1 present in their fur, making humans less allergic. So far, the vaccine has been "tolerated well" and hasn't had an "overt toxic effect" in test subjects.

Scientists involved in the study say that the vaccine could benefit both people and cats alike. "Both human subjects and animals could profit from this treatment because allergic cat owners would reduce their risk of developing chronic diseases, such as asthma, and become more tolerant of their cats, which therefore could stay in the households and not need to be relinquished to animal shelters," explained researchers.
